Hi fatty;

It is not wise to just go handing your email address out like that. The asker here might be legitimate but anyone on the internet can see it also. You are leaving yourself open to spammers and hackers as well as numerous bots.

You might have been unaware of that. If you put it back I will assume you are willing to chance it and I will not interfere further.

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

it actually doesn't equall fifteen it equals 3026144400. becuase you have to find out what 1*2 is and the product of that *3 and the product of that #4 and the product of that *5 and keep going until you get to the product of 15.

15! means 15 facturo or something like that which is basically the product of 15

Re: maths product

15! is not the product of 15, it is the product of all natural numbers less than 15. Maybe that is what you meant?

Hi rstakits!

Using N for "a number" that would be 800 times N, or 800N or 800xN where x means times.

If you have a collection of numbers like {3,10,5} then X{3,10,5}=1x3x10x5=150 would be theproduct of the numbers in the collection. We in essence "scale up" the 1 by the numbers in theset. If there are no numbers in the set like the set { } then we don't have anything to scale the1 up by so we just get the 1. X{ }=1.

So this gives us a short notation for multiplying any collection of numbers we want. If all the numbers in the set are the SAME then we have exponentiation. X{2,2,2}=1x2x2x2=2^3, whichis called "two cubed."

That may be more than you wanted, but maybe it will help somewhere along the line.

Have a stupendous day!
